But Lance wasn't the only one tweeting about his new arrival! Tweeting under the name "@CincoArmstrong," Lance set up an account for his unborn baby. "I got 2 arms, 2 legs, a nickname, and i'm 2 inches long. See y'all in October.." was the first entry, followed up by "I'm now the size of a lemon, 3.5 inches long, and weigh 1.5 ounces. And oh yeah, I'm on Twitter."

The baby, which will either be a Jack or Olivia, already has 1300 followers ... and counting!
